When nonwetting fluid displaces wetting fluid in a porous rock many rapid pore-scale displacement events occur. These events are often referred to as Haines jumps and any drainage process in porous media is an ensemble of such events. However, the relevance of Haines jumps for larger scale models is often questioned. A common counter argument is that the high fluid velocities caused by a Haines...

Global climate change is happening but may be mitigated by the technology of geological carbon dioxide ( CO 2) sequestration. To gain comprehensive insights into this approach, we perform pore-scale simulations displacement between two miscible fluids in porous media using a new multiple-relaxation-time lattice Boltzmann model. This study marks first attempt to investigate viscous fingering dyn...

In order to safely store CO2 in depleted reservoirs and deep saline aquifers, a better understanding of the storage mechanisms of CO2 is needed. Reaction of CO2 with minerals to form precipitate in the subsurface helps to securely store CO2 over geologic time periods, but a concern is the formation of localized channels through which CO2 could travel at large, localized rates. Pore-scale networ...
